Short throw projector mount with micro-adjust feature
View Patent ↗A short throw projector mount enabling a finely tuned distance adjustment and/or finely tuned height adjustment of an attached projector. The mount includes a wall interface, a projector positioning head, and an elongate arm operably coupling the wall interface and the projector positioning head. A first end of the arm is coupled to the wall interface, and the projector positioning head is operably coupled proximate an opposing second end of the arm such that the projector positioning head is shiftable along a longitudinal axis of the arm. The arm further includes a positioning mechanism arranged to selectively drive shifting of the projector positioning head. A vertical positioning mechanism may be provided to shift the projector vertically relative to the wall interface.
